Mud of anhydrous artillery piece is to be used at stemming the plasticity of blast furnace taphole is fireproof material, blast furnace not when taphole iron, mud of anhydrous artillery piece is blocked up inside iron mouth, be in mouth of blast furnace iron and crucible union department to fashion slimy package, rehabilitate of in order to by the crucible brick line of corrode caustic, make iron mouth maintains certain deepness, when blast furnace taphole, the center of mud of anhydrous artillery piece that is blocked up inside iron mouth is gotten by mouth machine an a narrow passage providing the only means of access to a certain place, eliminate broken bits iron. For this requirement anhydrous mud of prepare Chinese medicine by roasting it in a panbig gun maintains stability of diameter of iron mouth a narrow passage providing the only means of access to a certain place, taphole speed is even,
Blast furnace taphole should repeat for many times everyday open and block a mouth up, molten iron and slaggy shed classics iron mouth, prepare Chinese medicine by roasting it in a pan to anhydrous slimy happening high temperature reacts physico-chemically, mud of anhydrous artillery piece is eroded to reach attaint. If anhydrous prepares Chinese medicine by roasting it in a pan slimy quality is not stabilized, can arise a series of problem, if iron mouth ruptures, iron mouth deepness is more shallow, affect condition of iron mouth job, drop iron mouth percent of pass, affect the normal production of blast furnace. Accordingly, the to iron mouth maintenance of stand or fall of quality of mud of artillery piece of blast furnace anhydrous is having conclusive effect on certain level.
Aggrandizement smelt and blast furnace long life change a project to already made the main work that at present contemporary blast furnace produces. The aspect is changed in blast furnace long life, daily taphole uses mud of prepare Chinese medicine by roasting it in a panbig gun to have very good effect to the maintenance of blast furnace crucible, and aggrandizement smelt and job of blast furnace long life used mud of prepare Chinese medicine by roasting it in a panbig gun to raise increasingly slashing requirement to taphole again, to satisfy these requirement taphole anhydrous mud of prepare Chinese medicine by roasting it in a panbig gun must have a few character.
1. safety starts to talk, can stabilize fill, caking property and plasticity are good, have good work performance, the mouth is easy
2. agglomeration is good, curing time is short, systole of the bulk after agglomeration is small at the same time;
3. stabilizes taphole, can fast starting a hole, starting a hole is easy, without the destruction that the taphole aperture that brings because of starting a hole maintains
4. is able to bear or endure erode, have counteractive high temperature molten iron and erode ability slaggily, be able to bear or endure erode capability is strong, diameter of iron mouth enlarge is slow
5. protects crucible, stabilize iron mouth deepness, the caking property with mud of old artillery piece is good, agglutinate sex is tall
Protective crucible changes the job to have important sense to blast furnace long life, must ask for this anhydrous prepares Chinese medicine by roasting it in a pan mud is in smooth-going taphole while still can maintain stability and enough iron mouth depth, in order to reduce taphole all round of crucible charcoal brick mar, achieve the goal that protects crucible thereby. At present manufacturer of production of mud of anhydrous artillery piece passes those who promote raw material grade and efficient additive to introduce wait for a method to promote function of mud of anhydrous artillery piece the demand with taphole of contented blast furnace. But the technical cost that the application of these technical measure raised mud of high-powered anhydrous artillery piece, reduced its sex price to compare. Composition of chemistry of leveling alumina product and mine photograph are stabler, in view of this, the palm corundum of case of the high price in using leveling alumina to replace mud of high-powered anhydrous artillery piece is compared with promoting its sex price.
Choose leveling alumina to be able to replace the palm corundum pellet in mud of high-powered anhydrous artillery piece, do not reduce its performance characteristics, the result that comparatives with mud of groovy and anhydrous artillery piece was obtained in real industry try out, because this prepares Chinese medicine by roasting it in a pan in high-powered anhydrous slimy raw material is chosen in the leveling that can use quality stabilize is aluminous, and conduce to raise its sex price to compare. Relative to at alumina of natural high grade character, leveling alumina pledges the quantity is stabilized relatively, the problem of quality of mud of anhydrous artillery piece that because the wave motion of aluminous quality is caused,can avoid, have very big profit to the stability of quality of mud of anhydrous artillery piece; Look from the notion that can develop continuously additionally, the promotion application of leveling alumina conduces to the aluminous natural resources with increasingly meager protection.
Quality inspection mixes mud of anhydrous artillery piece examine standard:
1.Contain carbolic amount, add the accuracy of coke certainly, the volume that contain carbon is higher, of coke deserve to compare bigger, conversely, deserve to compare smaller.
2.Volatilize cent, decide the accuracy of bitumen, the volatilization of mud of anhydrous artillery piece basically comes from bitumen, with this examination bitumen matchs the accuracy of the quantity.
3.Weigh the time grinding mud of mud of anhydrous artillery piece through screening granuality, the time that grind mud is longer, the size of mud of prepare Chinese medicine by roasting it in a panbig gun is smaller. Because the production of mud of this anhydrous artillery piece needs the reasonable time that grind mud.
4.Detect equestrian summer worth, ma Xia is worth is the detecting with important mud of anhydrous artillery piece project, equestrian summer worth is to be on equestrian summer instrument, imitate prepares Chinese medicine by roasting it in a pan mud is below iron opening position, have the cover or daub with plaster of prepare Chinese medicine by roasting it in a panbig gun inside instrument of park horse summer extruding, the mashed vegetable or fruit of prepare Chinese medicine by roasting it in a panbig gun that the test gives is soft the index of strong pitch, it is an unit with Mpa, it is the index that checks sex of clay sculpture of anhydrous artillery piece,
Of quality of mud of anhydrous artillery piece examining is to ensure what anhydrous prepares Chinese medicine by roasting it in a pan mud applies at blast furnace taphole is basic, also be the standard of quality of mud of reaction anhydrous artillery piece.
Good stuff cannot leave good facility, the production of mud of anhydrous artillery piece cannot leave to produce the equipment of mud of anhydrous artillery piece, machine of crowded mud of mud of anhydrous artillery piece is the main equipment that mud of anhydrous artillery piece produces, basically prepare Chinese medicine by roasting it in a pan anhydrous carborundum of fireproof raw material reachs mud tar, jiao Mo, the fireproof raw material such as anthracene oil adds the extrusion after lukewarm agitate, basically use at mud of anhydrous artillery piece extrusion, machines and tools of crowded mud of mud of anhydrous artillery piece has heat temperature can charge figure of function, crowded export but custom-built, design reasonable, structure the characteristic such as simple, wear well, facilitating maintenance.
Mud of anhydrous artillery piece squeezes the operation note of slimy machine:
Each place, spare parts is in equipment of aircraft of crowded mud of mud of 1. examination artillery piece whether is there injury, knock against in carrying, whether to affect machine of mud of prepare Chinese medicine by roasting it in a panbig gun to run normally;
